Answer:
Rearranging the options we have;
a. $73
b. $75
c. $55
d. $78
From which the correct option is;
b. $ 75.
Step-by-step explanation:
To solve the question, we note that
Number of hours worked last week by Maria = 15 Hours
Amount earned by Maria for work last week = $ 112.50
Therefore by finding the hourly rate, that is how much Maria is being paid per hour, we get
15 Hours = $ 112.50
Therefore dividing both sides of the equation by 15 we get
15 Hours/15 = $ 112.50/15 which gives
1 Hour = $ 7.50
To find out how much will she earn if she works for 10 hours, we have
1 Hour = $ 7.50
Therefore multiplying both sides of the equation by 10 we have,
1 Hour × 10 = $ 7.50 × 10
10 hours = $ 75.00
That is she would earn $ 75.00 in 10 hours.
